<p>Provided are an inter-network device communication method, a related device and a system. A signalling link with a communication network element of a first network is established to receive interaction information which is sent by the communication network element through the signalling link of the first network and which needs to be received by a network server of a second network, a data flow which is sent by a terminal and needs to be received by the network server is acquired to package the interaction information and the data flow, so as to generate a service flow, and the service flow is sent to the network server by means of the second network. The interaction information between the communication network element of the first network and the network server of the second network is transmitted while transmitting the data flow, the application of network resources is reduced, and the first network directly accessing the second network is avoided. By establishing a secure signalling connection communication tunnel between a CT network element of the first network and the network server of the second network, the first network is prevented from being attacked by a risk factor of the second network, deployment resources of the CT network element are saved, and the speed of inter-network device information communications is improved.</p> |
